!code_source

After this command, UDO expects text which has been written
using the selected encoding. To switch back to the system encoding,
use this command again with the system encoding name.
Here is an overview about the available encoding names:
UDO supports various codepages for various systems. Below you see
a list of all currently supported systems and codepages, some of which
with multiple descriptors for the same codepage. It doesn't matter if
you use these descriptors upper- or lowercase. (The descriptors base
on the former UDO descriptors and on those supported by the Unix
command iconv.)

Important: If you have used latin1
in your old UDO documents, you should switch it to e.g.
cp1252 because UDO used to assign Windows codepage
1252 to it before version 7 which correctly assigns ISO-8859-1 to it!
